Antennas- vertical antenna (for installing on the surface)- directional antenna YAGI + combiner of 8 WCDMA/GSM channels (for distribution of load to different base station of Mobile Network Operator). It is recommended for 16/24/32-channel devices

General Description

Multifunctional GSM-card for 4-8 GSM-channels is useful for receiving and placing calls in mobile networks (GSM) as well as receiving and transmitting SMS, sending USSD-requests. Integration of the GSM-card in company's telephone system provides phone calls cost reduction especially for «office — mobile phones» direction. Also the GSM-card is the fastest and easiest way to establish telephony communication in locations where landlines are unavailable or costly.

The model enables user to insert up to 8 SIM-card into SIM-holders or commutate SIM-cards remotely using remote SIM-management technology provided by SIM-server Polygator.

The card operates under OS Linux (all *NIX systems are supported). It is compatible with IP-PBX Asterisk thanks to native Asterisk-module (PGGSM) and Linux-driver by Polygator. Under Asterisk software the card provides maximal range of features and functions. By using GSM-card without IP-PBX Asterisk (with Linux-driver only) it is possible to reach GSM-modules as a pool of GSM-modems. All GSM-modules available in OS Linux locally (as TTY devices) or via TCP/IP (with help of ser2net Linux software) as a pool of Ethernet-modems. In both cases modules are controlled by АТ-commands.
